Well, sort of:
Under the picture of the woman driving is text saying 'Say YES to women driving'.
Sorry for the poor quality of the pic, but I had to quickly snap it while driving. I was extremely shocked to see a sticker as brazen as this one, especially in Riyadh (this sort of stuff is more expected from the more liberal Jeddah).
Of course, not everyone shares the above driver's sentiments. Abu Ilyas has an interesting picture from the other side.
